Feed is the basis for the development of animal husbandry production. There are many kinds of agricultural and sideline products in Yunnan Province and there are a wide range of feed sources. During the "Eighth Five-Year Plan" period, compound feeds and concentrated feeds gradually gained popularity in rural areas and played an extremely important role in animal husbandry production. In particular, the promotion of economical and practical livestock and poultry concentrate feeds was a combination of provincial conditions, convenience to the masses, and full development. Using the effective means of agricultural and sideline products and processing by-products, the advantage of the feed resources in the mountainous areas has been exerted, and the rapid development of the animal husbandry economy has been accelerated. However, there are also a few areas in the use of concentrated feed, there are problems with unreasonable ingredients, unscientific use methods, and other issues, concentrated feed can not play its due economic benefits. Now the correct use of concentrated feed methods and techniques are described as follows: 1, the benefits and role of the use of concentrated feed (1) the use of concentrated feed scientific and convenient and effective. Concentrated feed is a high-efficiency feed formulated with plant protein, calcium, phosphorus, trace elements, and salt through science. Farmers can formulate compound feed by just adding appropriate amounts of corn, bran, and other energy feeds or agricultural and sideline products. In areas with inconvenient transportation and a large number of agricultural and sideline products, the use of compound feeds can fully develop and utilize local feed resources, reduce costs, increase feed utilization, and increase farmers' income. (2) The use of concentrated feed is beneficial to ecological protection. The application of concentrated feed has laid a foundation for scientifically raising livestock and feeds in rural areas. It has played a positive role in reducing the labor intensity of farmers, reducing deforestation and protecting vegetation, and has played a significant role in protecting the environment and regulating ecological balance. (3) Promoting the use of concentrated feeds will facilitate the development of the aquaculture industry. General concentrated feeds account for 15% to 30% of compound feeds, while most of the other 70% to 85% feedstuffs are produced by farmers themselves. The cost is low, and the promotion of the use of concentrates will improve the efficiency of raising livestock for the majority of farmers and promote the breeding industry. Development is of great significance. 2, should pay attention to the purchase of concentrated feed (1) to understand the quality standards of concentrated feed. Concentrated feed is not a feed concentrated by processing, but is a mixture of high-protein feed, mineral feed, and trace element additives in accordance with the animal's nutritional needs. Its quality is determined by the level of biochemical titers that make up the ingredients. In particular, whether the content of amino acids meets the animal's requirements for nutrition does not depend on the amount of certain raw materials. Therefore, the quality of the concentrate depends on whether the content of various compounds in the ingredients is scientific and reasonable, and whether it meets the needs of animal growth and development. (2) Purchase concentrated feed according to the type of farmed animals. Some farmers do not purchase the enriched feeds in accordance with production needs. As a result, they cannot only play the role of concentrated feed, but also have a significant adverse effect on the growth and development of livestock and poultry. Therefore, livestock and poultry of different types, different growth stages and different production uses need to use different concentrated feeds in order to give full play to the advantages of concentrated feed and produce good economic benefits. If the pig's concentrated feed is used to feed pigs, the calcium and phosphorus content in the chicken concentrate feed will cause metabolic disorders of calcium and phosphorus, poor digestion and slow growth. Conversely, feeding chickens with concentrated pig feeds is even more a violation of science. Chickens not only grow slowly, affect egg production, but also cause other diseases and cause greater losses. 3, how to buy concentrated feed (1) look at the product packaging. There are standardized packaging methods for concentrated feed products, with strict quality requirements and hygienic requirements. When purchasing, pay attention to the oldness and the date of production of the outer packaging. If the appearance is out of date and the writing image is unclear, the product has been stored for too long or is counterfeit. Products can not be purchased. (2) Look at the labels and trademarks. Qualified concentrated feed products should have product quality inspection certificates, registered trademarks and instructions. The specification shall include the product name, feeding object, product registration number or approval number, raw material composition, product component analysis guarantee value, usage and usage, net weight, production date, shelf life, factory name, site and product standard number, etc. Recommended formula, feeding method, expected feeding effect, preservation method, precautions, etc. Products with the above logos and instructions are generally regular products and can be purchased. (3) Look at the appearance of the product. When buying concentrated feed, it is necessary to see whether the color is uniform, whether the flavor is fragrant, whether there is impurities, whether the sachet packaging is intact, whether the weight is consistent with the description, and whether the cake is agglomerated. 4, the correct use of concentrated feed method (1) buy concentrated feed should not buy too much at one time, according to the amount of culture to buy in order to prevent storage time is too long or deterioration. The general storage time of concentrated feeds should not exceed 2 months. Stored areas should be kept cool, dry and ventilated. (2) Concentrate feed is a kind of high-protein feed. Enriched feed must be filled with enough energy feed, such as corn, broken rice, bran, etc., to become full-priced compound feed, and the amount of bran should be controlled at 10% when used together. No more additives or protein feeds should be added to avoid feed wastage, affecting the growth of livestock and poultry, and even causing poisoning. (3) The correct ratio. When concentrated feeds are used, they must be formulated in the proportions recommended in the product specification in order to ensure a balanced diet and achieve the desired results. When preparing feeds, the proportion of concentrated feed should not exceed 30%. If you formulate it on your own, you will not be able to save on feed and reduce costs. When preparing, it is necessary to mix a small amount of feed ingredients with the concentrate before mixing with a large amount of feed ingredients. (4) Feeding should be scientific. Concentrated feeds are best not to be fed separately, and they must be formulated into compound feeds before feeding. Dry feeds should be used as raw materials or mixed immediately after the tides, ie, they should be mixed and fed immediately. It is not necessary to cook or take other methods for reprocessing to prevent the nutrients contained therein. Material denaturation or failure. When feeding, appropriate amounts of green fodder can be added. If long-term feeding of green fodder, pay attention to regular deworming, which can increase the utilization of feed and increase the efficiency of raising livestock.
